    • A connecting structure for high frequency circuits is provided, with which components can be readily replaced, and which does not require high assembly accuracy and is applicable in a broad band. First and second circuit boards each having strip lines on top surfaces thereof are placed to secure a gap therebetween. Patch portions each constituting a resonator are formed by extending the width of the strip lines, and a supporting member of a foam material is placed on the top of the patch portion formed on the first circuit board. A parasitic element made of a dielectric material is cantilevered by the supporting member. The free end side of the parasitic element is placed above the patch portion formed on the second circuit board while securing a predetermined space between the parasitic element and this patch portion. A strong electrical connection is established by the parasitic element that electromagnetically couples non-continuing portions, thereby making it possible to cut a direct current.
    • 提供了一种用于高频电路的连接结构,可以容易地更换部件,并且不需要高的组装精度并且可以应用于宽带。 每个在其顶表面上具有带状线的第一和第二电路板被放置以固定它们之间的间隙。 构成谐振器的贴片部分通过延长带状线的宽度而形成,并且泡沫材料的支撑部件被放置在形成在第一电路板上的贴片部分的顶部上。 由电介质材料制成的寄生元件由支撑构件悬臂。 寄生元件的自由端侧被放置在形成在第二电路板上的贴片部分的上方,同时固定寄生元件和该贴片部分之间的预定空间。 通过电磁耦合非连续部分的寄生元件建立强电连接,从而可以切断直流电。

    • A flat heat exchange tube comprises an upper wall, a lower wall, right and left side walls interconnecting right and left side edges of the upper and lower walls, and a plurality of reinforcing walls connected between the upper and lower walls, extending longitudinally of the tube and spaced apart from one another. The tube has parallel fluid passages formed inside thereof and extending forward or rearward. Each of the reinforcing walls has a plurality of communication holes arranged at a spacing longitudinally thereof for holding the parallel fluid passages in communication with one another therethrough. The upper surface of the lower wall is provided at a portion thereof forming each of the fluid passages with a plurality of turbulence producing portions extending over the entire width of the fluid passage and arranged at a spacing longitudinally of the passage.

    • This invention relates to a writing instrument wherein a temporary ink storage member made of a synthetic resin injection molded article is sandwiched between a pen tip and an ink tank. In the present invention, a flange portion for fitting to a predetermined apparatus, which is positioned around an outer peripheral portion of the temporary ink storage member, is formed integrally with a shaft made of a synthetic resin injection molded article. In embodiments of the invention, the temporary ink storage member is made flexible, the shaft is made of a material which is softer than that of the tip holder, and the tip holder is used as a writing thickness display member. The temporary ink storage member can be used as an ink color display member and a cap is used as an application display member. In other embodiment, the cap can be fitted selectively in accordance with types of writing instruments.
